1990–2008: Early life and career beginnings

Park Sang-hyun was born in Busan, South Korea, but grew up in the Philippines. He has two older sisters, Sandara and Durami. Aside from his native Korean, he is also fluent in English and Tagalog, and can speak conversational Mandarin and Japanese.

His eldest sister, Sandara, achieved nationwide fame in the Philippines in 2004 after becoming the runner-up on the first season of Star Circle Quest, a talent search reality competition. He first appeared on national television when he attended the finale with his mother. Later on, as his sister began her hectic activities as a celebrity, a crew from one of South Korea's biggest television agencies recorded her daily life in the documentary My Name Is Sandara Park. This marked Thunder's first ever appearance on South Korean television.

Sandara's eventual decision to pursue activities in their home country led to their family's return to South Korea in 2007. By this time, Thunder had finished secondary education in the Philippines. It was later on revealed in a magazine interview that he had originally decided to pursue a professional career as a soccer player, specifically as a midfielder. He gave up and instead started auditioning for entertainment agencies, one of which was JYP Entertainment. He had taken dancing workshops offered by Sandara's home network back in the Philippines.

Thunder eventually became a trainee under LOEN Entertainment, where he met IU. He appeared in IU's debut music video for her song "Lost Child" and was also seen in a couple of videos with her wherein they sing Big Bang's "Lies" and Super Junior's "Sorry Sorry."
